Render time in build is greater than that in editor

Hey Guys,
I was profiling my level and I am getting very different values for GPU render times when profiling it in editor using GPU Visualizer vs. checking Stat GPU values when playing a windows Build.
Total render time when checking in editor using GPU Visualizer is 4.55 ms while total render time in build checked using Stat GPU command is 12.29 ms.
Please note that I am playing the scene in VR.

Can anyone explain to me why there is such a differences in the readings? Thanks for your help.
